[0002] Plant-based insulating oil is an environmentally friendly, flame-retardant liquid dielectric. Its main component is triglyceride, and its flash point exceeds 300°C, meeting the requirements for high flash point insulating oils.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1:

[0022] Please see Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a multi-stage separation device for the production of plant-based insulating oil, including a filter box 1. A primary filter screen 2, a secondary filter screen 3, and a fine filter screen 4 are fixedly connected to the inner wall of the filter box 1 from top to bottom. Each of the primary filter screen 2, secondary filter screen 3, and fine filter screen 4 has a nozzle 5 at its bottom. A connecting pipe 6 connects to the rear side of each nozzle 5. A hollow block 7 is fixedly connected to the right side of the back of the filter box 1. A fan 9 connects to the top of the hollow block 7. An exhaust pipe 10 connects to the bottom of the back of the hollow block 7. A solid [unclear - possibly a component or device] connects to one side of the exhaust pipe 10. One side of the fixed pipe 11 is connected to the connecting pipe 6. A motor 12 is fixedly connected to the bottom left side of the back of the filter box 1. A lead screw 13 is fixedly connected to the output end of the motor 12. A threaded sleeve 14 is threadedly connected to the surface of the lead screw 13. One side of the threaded sleeve 14 is fixedly connected to the fixed pipe 11. A slide rod is slidably connected to the top of the inner cavity of the threaded sleeve 14. One side of the slide rod is fixedly connected to the filter box 1. A frame is fixedly connected to the right side of the filter box 1. A hollow pipe is connected to the bottom of the frame. A control valve is movably connected to one side of the hollow pipe.

[0023] The specific function of this technical solution is as follows: During operation, the material is filtered sequentially through the primary filter 2, the intermediate filter 3, and the fine filter 4 to remove impurities. Simultaneously, the blower 9 and the motor 12 are started, and gas is sprayed out through the exhaust pipe 10, the fixed pipe 11, the connecting pipe 6, and the nozzle 5. The motor 12 drives the lead screw 13 to rotate, the lead screw 13 drives the threaded sleeve 14 to move, the threaded sleeve 14 drives the fixed pipe 11 to move, the fixed pipe 11 drives the connecting pipe 6 to move, and the connecting pipe 6 drives the nozzle 5 to move, thus performing reverse exhaust and preventing the primary filter 2, the intermediate filter 3, and the fine filter 4 from clogging.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a heating mesh 8 is fixedly connected to the inner wall of the hollow block 7. A housing 15 is connected to the left side of the bottom of the filter box 1. A stirring roller 16 is movably connected to one side of the housing 15. A pulley 17 is fixedly connected to the rear side of the stirring roller 16 and the front side of the surface of the lead screw 13. A belt 18 is sleeved on the surface of the pulley 17. Heating plates 19 are fixedly connected to both sides of the bottom of the inner cavity of the housing 15. The rear side of the inner cavity of the housing 15 is movably connected to the stirring roller 16 through a bearing. Support legs are fixedly connected to the bottom of the filter box 1 and the housing 15. A round hole is opened on the back of the housing 15, and a sealing ring is fixedly connected to the inner cavity of the round hole.

[0026] The specific function of this technical solution is as follows: The material will then enter the inner cavity of the shell 15 and be heated by the heating plate 19. The air will also be heated when it passes through the heating mesh 8. The hot airflow will come into contact with some of the material, thereby playing an auxiliary heating role. The rotation of the screw 13 will also cause the stirring roller 16 to rotate, thereby stirring the material and making the material heated evenly, thus facilitating the quick separation of moisture.

[0027] Working principle: During operation, the material is filtered sequentially through the primary filter 2, intermediate filter 3, and fine filter 4 to remove impurities. Simultaneously, the blower 9 and motor 12 are activated, and gas is ejected through the exhaust pipe 10, fixed pipe 11, connecting pipe 6, and nozzle 5. The motor 12 drives the lead screw 13 to rotate, which in turn moves the threaded sleeve 14. The threaded sleeve 14 moves the fixed pipe 11, which in turn moves the connecting pipe 6. The connecting pipe 6 then moves the nozzle 5, resulting in reverse exhaust. This prevents the primary filter 2, intermediate filter 3, and fine filter 4 from clogging. Subsequently, the material enters the inner cavity of the housing 15 and is heated by the heating plate 19. The air passing through the heating mesh 8 is also heated, and the hot airflow comes into contact with some of the material, thus providing auxiliary heating. The rotation of the lead screw 13 also causes the stirring roller 16 to rotate, agitating the material and ensuring uniform heating, thereby facilitating rapid separation of moisture.
